Voice recognition includes two blocks – the separation of the alarm and recognition of sounds. When you split the signal recorded sound is coming from the object of study, and the audio data received from other parties, are ignored. As a result, the robot is able to recognize the voice at a distance of up to 2 hours for the recognition of the audio data transmitted through Wi-Fi to an external server, where the process itself. The results are transferred back. Robot is able to give instant response when required, but during a conversation with people is necessary reaction rate 100 ms or more, so use a special server, say in the company.
